### 4.2.12. Schemes for Further Study

X500

  The mapping of x500 names onto URLs is not defined here. A decision is required as to whether "distinguished names" or "user friendly names" (ufn), or both, should be allowed. If any punctuation conversions are needed from the adopted x500 representation (such as the use of slashes between parts of a ufn) they must be defined. This is a subject for study.

WHOIS

  This prefix describes the access using the "whois++" scheme in the process of definition. The host name part is the same as for other IP based schemes. The path part can be either a whois handle for a whois object, or it can be a valid whois query string. This is a subject for further study.

NETWORK MANAGEMENT DATABASE

  This is a subject for study.

NNTP

  This is an alternative form of reference for news articles, specifically to be used with NNTP servers, and particularly those incomplete server implementations which do not allow retrieval by message identifier. In all other cases the "news" scheme should be used.

  The news server name, newsgroup name, and index number of an article within the newsgroup on that particular server are given. The NNTP protocol must be used.

  Note 1.

    This form of URL is not of global accessability, as typically NNTP servers only allow access from local clients. Note that the article numbers within groups vary from server to server.

    This form or URL should not be quoted outside this local area. It should not be used within news articles for wider circulation than the one server. This is a local identifier for a resource which is often available globally, and so is not recommended except in the case in which incomplete NNTP implementations on the local server force its adoption.
